Hey everyone I have couple of questions. ill be glad if you can help me What are the switches S1 and S2 with their 3 positions doing? (couldn't find a nice simple explanation on the net, everyone everywhere uses the terminology like FPV and etc. i dont understand) If i'm a newbie and i dont want to try any Naza and pro modes, what position should i leave them in? I tried flying high, at the open area in the middle of the city. Once after 70, and another time after 100 meters it said thats the signal is weak and signal was being lost. I know i can make it go up to 500 meters, so how is it possible then? When i am making the HOME return, it lands the same place, like 10-15 meters away from the place it took off. I have it set to Home Return and Failsafe (30 meters, but it still didnt went up) So how can i adjust this, so it lands precisely closer to the place it took off?
